COIN-DELIVERY MACHINE.

Application filed April 22, 1922.

To all rfi/1.0772` 712,@1/ concern.'

Be it known that we, Ronnn'r Cr-fiInNs and Josnrrr lV. Ciirmvs, citizens ot the United States. residing at lVatei-town, in the county of Jefferson and State of Visconsin, have invented new and useful Improvements in Coin-Delivery Machines, ot which the following is a specification.

This invention relates to change-making and other coin-delivery machines, and its object is to provide a machine of this kind in which the coin-ejecting mechanism is power-operated, the power source being an electric motor. The machine is controlled by a series ot manually operated keys by means ot which a selector mechanism is operated to citect the ejection of the coins required to make up the sum of money to be thrown out, and these keys also operate to throw a switch which closes the energizing circuit ot' the motor, and to control a clutch by which the motor is connected to a shaft carrying: actuators tor t-he coin-ejector mechanism. The machine also embodies other novel and improved mechanism whereby the entire operation of ejecting the selected coin or coins is automatically effected after depressing the proper key, the parts being all restored to inoperative position after each operation. A safety device is also provided for preventing damage to the mechanism it the coin ejectors should meet with an obstruction.l and the actuating means ot' the ejectors are adjustable to impart to the latter a working stroke of the proper length.

(ther novel and improved details of construction and modes ot operation will be pointed out in the description appearing hereinafter.

ln order that the invention may be better unflerstood. reference is had to the accompanying drawings, wherein:

Figure 1 is an end view of the apparatus; Fig. 2, is va cross-section; Fig. 3 is a plan view with a portion ot a casing broken away; Fig'. 5L. is a section on the line i-l ot 2%; Fig. 5 is an enlarged side elevation of one of the units of a selector mechanism; Fig. (i is a view similar to Fig. r5 showing the parts in another position, and Fig. 7 is an enlarged elevation of a detent and other` parts associated with a switch mechanism.

Serial No. 556,028.

Referring speciiically to the drawings, the machineA is provided with a plurality of coin chutes 10 designed to support stacks of coins of various denominations. 1With each coin chute is associated an ejector finger 11 for pushing the bottom coin 'from beneath the stack. Ea ,h ejector 11 is carried by a slide block 12 mounted on a. guide stem 13, and connected by a link 1li to one end ot a lever 15 pivoted at its other end, asl shown at 16, to a suitable support 17. The lever 15 has a laterally extending arm 18 which is connected at its outer end by a link 19 to a collar 2O carried by a vertically reciprocatory stem 21. The collar 20 is loose on the stem 21, and on the latter are fixed abutments 22 and 23. Between the upper abutment 22 and the top ot the collar 20 is a spring Q41, the saine being coiled around the stem 21 and tending to hold the collar down against the lower abutment 23. This construction provides a yieldable connection between the stem 21 and the collar 20. The ejector finger 1l is given a forward or working stroke when the stem 21 is drawn downwardly, this motion ot the stein beingcommunicated to the collar 20 by the abutment 22 and the spring 24, and the downward movement ot the collar 20, through the link 19 and lever arm 18, causes the lever 15 to swing in a direction to advance the slide block 12 to give the finger 11 its ejecting stroke. lt the finger 11 should meet an obstruction, such a bent coin, no damage will be done to any parts oit the mechanism, as the coilar 2O is loose on the stem 21, and the blocking ot the iinger 11 will merely result in the collar 2() remaining stationary as the stem 21 continues to gio down.

The. lower end ot the stein 21 carries a support 25 tor a slidable tinger 2G, the same extending laterally' from the stem, and being adj ustablc to intercept a wiper member carried by a power-driven shaft 27. i This wiper consists of a radial arm 28 madel fast on the shaft Q7 and having adjustably fastened to its outer end a blade When the blade `29 strikes the finger Q6, the stem 21 is drawn down to give the inger 11 an ejecting` stroke as hereinbetore described, and the length ot this stroke can be very accurately adj-usted according tothe diameter of the coins by advancing or retracting the blade 29. The adjustable connection between the blade 29 and the member 23 may be made by a screw 30 passing into the latter through a longitudinal slot 3l in the former. The linger 26 is normally in retracted position out of the path ot the blade 29, and it is so held by a spring 32.

The stem 2l is supported by a pair ot vertically spaced plates 33 and 34 having alined apertures in which the stem slidably seats. A spring 35, anchored to the upper plate 33 and connected to the support 25, tends to hold the stem normally elevated, and after the downward working stroke or" thestem, the spring restores it to elevated position.

An ejector mechanism as hereinbei'ore de-V scribed is provided for each coin chute l0, and in order to select the ejector unit which will throw out the desired'coin or coins, the machine is provided with a bank of depressible keys 36, each having its stem 37 fitted at the bottom with 'one or more lugs 38 adapted to engage a corresponding member of yoke bars 39 pivoted at their ends, as shown at 40, to suitable supports 41. Beneath each yoke bar 39 is located a vertically positioned and slidable stem42, the upper end ot said stem having a head 43 which is pressed by the yoke bar when the latter is rocked by a finger 33 as the keyl stem 37 is pushed down. Each key stem 37 has aV restoring spring 44, and each stem 42 has a restoring spring 45 positioned between an abutment 46 on the stem and a bottom guide 47 in which the stem works, said guide being carried by the plate 34. The plate 33 also carries a guide 48 tor the stem 42.

A. stem 42 is associated with each stem 2l, the purpose of the former being to advance the finger 26 so that it may intercept the wiper blade 29 as hereinbet'ore described. In order that the stem 42 may function in this manner, its lower end is connected by a link 49 to a lever 50 fulcrumed at 5l to a depending bracket 52 carried by the plate 34. This bracket also supports an angle lever, one branch 53 ot which is pivoted to the bracket at 52a, whereas its other branch 54 is located at its extremity behind a side lug 55 on the forward end ot the finger 26. At the junction et the two branches 53 and 54 of the angle lever is a side pin or abutment 56 which rests on the lever 50. It will be evident from the foregoing vthat the downward movement ot the stem 42 causes the rear portion oi. the lever Vto swing upwardly, and through the abutment 56 to tilt the angle lever in such a direction that the branch 54 of the latter pushes against the lug and advances the finger 26 to come into the path of the wiper blade 29 as shown in Fig. 6. In order to hold the iinger advanced, the bracket 52 carries a latch hook 57 which drops into keeper notch 5S in the top edge oit the finger 26 when the latter is advanced as described.V lWhen the wipe-r blade 29 engages the advanced finger 26, the stem 2l is drawndown to eiiiect the operation or" the ejector finger 1l, and as the finger 26 now moves away 'from the latch 57, said finger is released so that it may be retracted by Ahe spring 32 when the blade 29"clears the iinger. lt will also be understood that the parts 37, 36, 39, 42, 50, 53 and 154 are restoredY to their normal position when the key 36 is released.

he drawings illustrate only one oi'- the ejector units, it being understood that the construction andv operation of the entire set ot units is the same. Fig. 4 shows one ot' the key stems 37 equipped with a single lug 38 ltor operating the stem 42 of a single unit, and second key stem having two lugs for operating the stems 42 ot' two different units. coin chutes l0, with a lcoin ejector unit for each chute. The chutes are designed to hold dollars, half-dollars, quarters, dimes, nickles and pennies, two dime chutes, two nickle chiites and ytwo penny chutes being provided. One hundred and one keys 36`are provided, and the selector mechanism is ranged so that any amount of change up to a dollar may be made by pressing one key.

i rllhe driving means for the shaft 27 is an electric motor 59 having its shaft 60 equipped with a worin 61 which 1s in mesh Vwith a worm-wheel 62 loose on the shaft 27,.

In order to establish a driving connection between the worm-wheel 62 and the shaft 27 there is'mounted on said shaft a clutch member 63 having its jaws adaptedv to engage n clutch jaws 64 on the worm-wheel. lhe clutch member 63 '1s splmed or otherwise connected to the shaft 27 so as to turn therey with and also be tree to slide thereon. To a base board 65 sujiporting the motor 59 is pivoted, as' vshown 65a, a clutch shifter il'ork 66 straddling the clutch member 63 and seating' in a circumferential groove 67 therein. The end of the shat't 27 adjacent to the clutch member 63 is fitted with a wiper 66, and between the latter and the clutch memberis a coiled spring 69 having a function to be presently described. The clutch in ber is held normally disengaged `from the clutch jaws 64 by a det-ent 70 engaging the tree end et the shitter 'forli 66. fthe detent 79 is pivoted, as shown at 7i, to a rocker arm 71a on a rock shaftj72 -journalcd at one Vend in a bearing 73 carried by the base board 65, and at its other end in a bearing 74 carried'by a bracket 75. To the detent-7O is connected a spring 76 which is anchored to the bracket 75 and tends to hold the detent down in engagement with the shifter fork 66. `IWhen the detent 70 is tripped cti' the shifter fork 66, the

latter is swung by a spring 77 in a direction to slide the clutch member 63 over into engagement with the clutch jaws 64V of the worm-wheel 62. The spring 77 is connected to the free end of the fork 66.

From one side of the detent projects apin 78 beneath which is located one end of a trip lever 79 fulcrumed to a support 80 on the'bracket 75. The other end of theV lever 79 is located beneath a foot piece 81 on the bottom of a vertically slidable stem 8la supported v in guides 82 carried by an upright support 83, which latter also carries bearings 83a in which the shaft 60 is Extending transversely of the series of yoke bars 39 and beneath th-e same, is a pivoted yoke bar 84 which is swung whenever the bars 39 are actuated by the key stems 37 as hereinbefore described. The bar 84 is supported by frame members 85, and it is held up against the bars 39 by springs 86 connected to its ends. To one end of the bar 84 is fastened a laterally extending finger 87 which is so positioned Y that it bears down against the upper end of the stem 81a to push the same downwardly when the'bar 84 is depressed. This downward movement of the stem 81fL swings the trip lever 79 in a direction to trip the detent 70 off the clutch-shifter fork 66, thereby releasing said fork and permitting the spring 7 7 to slide the clutch member 63 over into engagement with the clutch jaws 64 of the worm-wheel 62, to couple the latter to the shaft 27. The lever 79 is provided with a return spring 79' connected to its rear end and anchored to the bracket 75.

To the rock-shaft 72 is fastened a laterally extending arm 88 to the outer end of which is connected a coiled spring 89 anchored to a frame part 90. On the shaft 72 is also fastened a laterally extending arm 91 which is in the path of the wiper 68. After the shaft 27 has been coupled to the worm-wheel 62 as hereinbefore described, and made one complete revolution, the clutch member 63 is retracted to break the driving connection, this being effected by the wiper 68 now engaging the arm 91 and thereby rocking the shaft 72 in a direction to advance the detent 70-and reengage it with the fork 66, this movement of the shaft 72 being opposed bythe spring 89. lhen the wiper 68 slips off the arm 91, the shaft 72 is released, whereupon it is rocked by the pull of the spring 89 on the arm 88, in a direction to withdraw the clutch meme ber 63 from the clutch teeth 64 of the wormwheel G2, this action being effected by the detent 70 which is now engaging the fork 66 and is drawn back by the rocker arm 71;1L to which it is connected, said rocker arm swinging as the shaft 72 is rocked. lhen the clutch-member is drawn back as Clesc-ribed, the spring 69 iS Compressed Se that it operates as a brake to bring the shaftY 27 to a quick stop.

The switch mechanism which controls the circuit of the motor 59 is best shown in Figs. l and 7. A base plate 92 of insulating material carries a stationary switch contact 93 to which one side of the circuit is connected through a fuse 94. The other side of the circuit is Connected to' a movable contact 95 carried by a strip 96 of insulating material7 which latter, in turn, is carried by one of the arms 97 of an angle lever fulerumed at. 98 to a suitable support 99, the other arm of said lever being shown at 01, and extending into the path of a wiper 02 on the shaft-'27 when the lever has swung to bring the contact 95 into engagement with `the contact 93. The contact 95 is normally free of the contact 93 and it is so held by the angle lever being held by a detcnt 03 pivoted at 04 to a support O5. A. spring O6 connected to the lever arm 97' swings the angle lever in a direction to engage the contact 95 with the contact 93 when the detent 03 releases said lever, whereupon the circuit .of the motor 59 is closed. A guide O7 is provided for the free end of the lever arm 97.

The detent O3 is tripped off the lever arm 97 every time any one of the key stems 37 is operated. AS pointed out hcreinbefore, the Vdepression of a key stem 37 rocks the yoke bar 84, and hence in order to effeet the tripping of the detent when the key stem is pushed down, the bar 84 is provided with a depending stem O7 which is position-ed to engage an arm 08 extending laterally from the detent 03. A spring 09 connected to the detent 03 tends to hold it normally in engagement with the lever arm 97, and to bring it into engagement therewith when said lever arm is swung to disengage the contact 95 from the Contact The operation of the machine may be summarized as follows:

The operator presses down the key o6 which denotes the amount of money to be ejected.` The key is held depressed only momentarily, and may then be released. This operation selects the proper ejector mechanism, closes the circuit of the motor 59, and also couples the shaft 27 to the motor through the clutch mechanism Ah ereinbeforo described. The-shaft 27 is thus set in motion, and when the blade 29 strikes the ad-I vanced finger 26 as shown in F ig. 6, the ejector' mechanism is operated, and immediately thereafter the wiper 02 strikes the lever arm Ol -to swing said arm 97 in adirection to carry the contact 95 away from the contact 93 and thus break the'mo'tor circuit. At the same time, the vclutch member ,63 is criliseI-lgaged to breakthe ldriving conynection between 4the .motor 59 ,and the shaft elle fra 27,'so thatthelatter comes to av stop, and'all the parts'have now resumed their normal position, and are reset for the next operationf' `f Suitablesupporting frames will be provided for the various parts of the mechanism hereinbefore described, andthe apparatus is also provided with a casing in which the mechanism is housed, and as these are immaterial to the invention they have not 'been described in detail. One end of the casing is provided with an opening which exposes the switch mechanism, and this opening is provided 'with Va door 00 which .is shown swung 'open inBig` l. l
